Here you can find the latest changes and improvements.

2026-08-22
New (Loxone): Miniserver Gen. 1 cannot use HTTPS. There is now a separate HTTP link with the same collection dates. Newer miniservers keep using the normal link.
2026-08-22
Umweltprofis: The link is ready immediately. Dates appear once the calendar has been requested – for example by Home Assistant, Loxone or in the browser. This can take a few hours.
2026-08-21
Fix: Umweltprofis no longer freezes the page (white screen). Existing dates are still shown; otherwise you get an error message.
2026-08-21
New (Loxone): Enter your code in the guide – then you see your links, upcoming dates and ready-to-copy texts. After creating a link (Loxone integration), the same texts are ready on the results page. No more typing them by hand.
2026-08-21
Improved (Loxone): Only the next date per bin. After collection the date moves on (by default from 12:00). Reminders can use the days until pickup; the switch time can be changed in the guide.
2026-07-27
Improved: After link generation, only the results page with your links is shown (not the form above it). This makes it clear that the link is already ready and does not need to be created again. There is also a save reminder, and a page reload no longer creates a second link.
2026-07-27
New: In addition to CSV, iCal files (.ics) can now be uploaded directly.
2026-07-27
Fix (Loxone): The JSON API now only returns today's and future appointments. Loxone takes the first match per waste type – without this filter it often showed the first (already past) date from the CSV/year calendar instead of the next one.
2026-07-27
New: mzv-rotenburg-bebra.de has been enabled as a calendar source (waste calendar from MZV Rotenburg-Bebra, e.g. webcal.php).
2026-07-24
New: Calendar pages can now be scanned automatically for iCal and CSV links. If multiple calendars are found, the desired feeds can be selected and merged into one feed.
2026-07-24
New: kirchberg-wagram.at has been enabled as a calendar source (DPCalendar iCal from the municipality of Kirchberg am Wagram). The event limit has also been raised to 2000.
2026-07-24
New: scharnitz.gv.at has been enabled as a calendar source (residual and organic waste iCal feeds from the municipality of Scharnitz).
2026-07-22
New: Allowed calendar sources are now visible on a dedicated page. New iCal providers have also been enabled: muellapp.com, app.muellapp.com, art-trier.de, ical.abfallplus.de and kumberg.gv.at.
2026-07-22
New: CSV waste collection calendars can now be uploaded directly. The file is converted server-side into a local calendar and a personal XML/API link is generated as usual.
2026-07-22
Improved: Umweltprofis appointments are stored locally under cache/ after the first successful fetch. The feed keeps working even if Umweltprofis temporarily returns no data or address IDs have changed. A refresh is attempted every 7 days; if it fails, the last local snapshot remains active.
2026-03-28
Improved: The Loxone documentation has been revised and extended with a real-world example. The guide now shows step by step how a Virtual HTTP Input Command, a Formula Block for date conversion (Loxone time base vs. Unix timestamp) and a Virtual Status work together. Screenshots from Loxone Config and the User-App illustrate the setup.
2026-03-14
New: The JSON API now includes a "unix_date" field for each event – the Unix timestamp of the collection day at 12:00 noon (Europe/Vienna timezone). This allows smart home systems like Loxone to evaluate the date directly without manually parsing the date format.
2026-03-05
New: Waste types can now be filtered directly on the website. If a municipality has multiple residual waste frequencies (e.g. "Residual waste fortnightly", "Residual waste monthly"), unwanted types can be hidden via checkbox – the XML feed will then only include the selected types.

Improved: For municipalities with multiple collection zones (e.g. Attersee), interval information such as "fortnightly" or "seasonal bin" is now automatically appended to the waste type name, making "Residual waste fortnightly" and "Residual waste monthly" clearly distinguishable. Generic phrases like "on the specified date" are not appended.

Improved: The results page after link generation has been redesigned for clarity. Links with copy buttons, waste type configuration and setup instructions are now clearly structured. The copy button now works reliably.
2026-02-07
Known issue: Umweltprofis function currently not working for Linz and Rohrbach.

Improved: iCal links can now be created without the Waste OO app, and Google Calendar links now work as well.
